This invention relates to. duplex umbrellas and has for itsprincipal'object the construction of air umbrella having the functions of botliaparaso'l and a" storm umbrella.

Theinvention contemplates the provision of an umbrella provided with adoublecover.

the outer cover having theiusual' durable and Water shed'dingcharacteristics of the ordi' nary storm umbrella, whilethe inner covermay be made of thelmore expensive and delicately colored materials"usually foun'ddn parasols. The advai'it-age of this construction is thatthe user of the duplex umbrella need not be deprived of the satisfactionand ornamental effect attending the use of the. parasol, even though theweather be inclement nor is she subjected toth e I risk of spoil; in-g aparasoh'when caught in a sudden shower, since the outercover amplyprotects the cover beneath. I I,

In the preferred construction the outer and innercovers are preferablyspaced apart, whereby spotting fof theinner cover through drawing ofmoisture fromthe outer cover by capillary attraction is avoided. andthis spaced relation of the covers also, fulfills an- 7 other object ofthe .invention, which is to provide a heat insulating space for moreeflectively protect ng theuser of the umbrella from the heat and glareof the sun.

A still further object of the invention is to so construct a duplexumbrella that it will fold. into as small a space as that usuallyoccupied by the ordinary umbrella when folded.

Other objects of the invention will appear as the description of thepreferred embodiment of the invention proceeds.

In the drawings Figure 1 is a side elevation, partly in section, througha portion of an umbrella made according to my invention. parts thereofbeing omitted.

Figure 2'is a side elevation of the frame of the umbrella showing theupper set of ribs in position to permit the replacement of the inner.cover. Figure 3 is aview in detail, partly in section. showingconnecting means between the inner and outer sets of ribs.

Figure 4 is a section taken along the line 4-4 of Figure 3.

Figures 5'and 6 are respectively side and sectional views of'the riblugs to which the stays are attached.

Referring now in detail to the several figprovided with a cover 13. y 7this cover 1t is necessary to disconnect the ures,1 the numerallrepresents the staff of the umbrella provi'dedvat spaced intervals withthe thiihbles 2, '3' and 4; The lowermost of tllGSGxiS for theattachment of the stays ,5, the others beingarrangedfor the pivotalsupport:- of the inner and outer sets of ribs. Sziidlribs and stays areanchored to the thimbles in the manner customarily employed in thema'nufacturmof umbrellas.

The inner and out e'r'sets ofribsoneof each set being respectivelydesignated by the reference numerals'fi' and '7, are of usual constructron; but the inner ribs are preferably sligl1tly-sl1orterthan:the, outer ribs; Said sets .ofv ribs are preferal'ily joined-by means oflinks 8 and 9, of substantially equal lengthj the latter being connectedto suitable lugs 1O and 11 fixed to the ribs. By' means of the links 8and 9 the outer set of ribs'is W p in nformity to the Sha e or the innerset, the adjacent; ribs of the inner and-outer sets' being maintained inpa'rallel 7 isnr throughout the opening and closing movements of theumbrella and also when it is fully opened. The stays 5 are connected tothe lugs 11, and thereby indirectly serve as braces for the outer aswell as the inner sets of ribs.

The outer set of ribs is provided with a cover 12 which is constructedand applied in the usual manner. The inner set of ribs To apply vplace,said cover being provided with a central aperture 16 for thispurpose. The inner coveris also provided with apertures 17.

and 18. preferably faced by eyelets. which register with the lugs 11 and10, respectively.

and through which the pivotal connection of the links 8 and 9 with thelower set of ribs may be restored after the inner cover is in place.

It will be evident to those skilled in the art that I have devised aduplex umbrella in which the inner cover is fully protected from theweather by means of the outer cover, thereby making it possible to formthe inner rover ol" more expensive and delirale materials. Theconstruction also prorides an inert air space between the inner andouter movers and at the same time prevents spotting of the inner coverby moisture which might be drawn by capillary aetion through from theouter cover it the rovers were in rontaot. The detachable links('onneetiiu): the inner and outer sets of ribs provides a l'aeilv meanswhereby the umbrella may be ro-eovered when neressar} and the provisionoil? the pivotal links 8 and 9. of substantially equal lengthpern'iitsthe closing ol the umbrella into as small a space as isoccupied by an ordinary umbrella when closed, (lite to the flatteningoi" the pai.'allelo- Qlllll defined by the inner and outer ribs andlhelinks S and 9, incident to the Closing movement of the umbrella.

While I have herein described what I be have to be a practicalembodiment of the invention it is to be understood that numerous changesin the eonstruolion and arrangeinent oi the parts may be made without restrieting: the scope of the invention.

. airing dtaserihod my invention what I olaiin asneu' and desire tosecure by Letters Patent, isz-- o 1. A duplex umbrella comprising astaff,

inner and outer sets oi ribs supported by said stall in spaced relation,separate covers carried by said sets of ribs and means conhurting: saidsets of ribs at intermediate points and at points substantiallyperiphoral. For warning the outer set of ribs in innifm'initv to theshape of the inner set.
